Catch Basins

Precast concrete catch basins are designed to drain excess stormwater and groundwater from paved streets, parking lots, and sidewalks. Gainey’s precast concrete catch basins provide an alternative to poured-in-place or bricked structures. Quality, economy and efficiency are increased by using precast drainage structures. D.O.T.D approved!

Custom Sizes Available!
  • Straight base or extended base sections available.

  • Riser sections as required.

  • Various sizes from 12”x12” to almost any large structure needed.

Manholes

Precast concrete manholes are used in sanitary sewer and storm drain systems for  maintenance access, observation points, changes in pipe size or direction, and junctions for multiple pipes.

Options
  • Straight base or extended base sections available.

  • Riser Sections in 1’, 2’, 3’, and 4’ Sections

  • Eccentric Cones in 2’ and 3’ Sections

  • Grade Rings in 4” and 6” Sections or as Required

Lift Stations

Whenever possible, wastewater systems employ the force of gravity to transport waste from homes and businesses to centralized treatment facilities.  But what happens when gravity decides to work against you? Lift stations or pump stations must be installed to “lift” wastewater to a higher elevation where it can continue to flow by gravity.

The next time you encounter a lift station on a set of plans, decide what part you really want to do and let us do the rest.

UniStorm

The “UniStorm” provides primary treatment of stormwater using precast manholes. The Unistorm system employs low-head loss internal flow diffusers and flow distributors to reduce stormwater turbulence and improve flow distribution. This allows on-line operation to eliminate pollutant bypassing during high-intensity rainfall events. Its design allows it to help you meet the EPA goal of 80% TSS removal efficiency and 40% phosphorus removal. Shallow sump depth of 4-5 feet reduces excavation costs and facilitates pumpout. Unistorm systems are ideal for sites with limited space and/or difficult soil conditions.

ESK Koala

ESK Koala is the latest in European Technology for High Efficiency Oil Water Separation. Through the application of coalescing media the ESK achieves removal efficiencies as low as 5 PPM (Parts Per Million) at flow rates in excess of 5000gpm, making it one of the most competitive high efficiency oil/water separators in the country.

Optional accessories include catastrophic spill valves, high level alarms, and high efficiency grit chambers. The ESK Koala is the perfect product for your industrial or commercial application.
